Planetary automatic gear box, has outer lamellae and inner lamellae, where surface of one of the lamellas is uneven in disengaging condition of multi disk clutch, so that lamella is axially flexibly compressable

摘要

The gear box has outer lamellae (4, 5, 6, 7) and inner lamellae (1, 2, 3), where the surface of one of the lamellas (5) is uneven in a disengaging condition of a multi disk clutch, so that the lamella (5) is axially flexibly compressable. The lamella (5) lies planar to friction linings (14,15) of two directly joining lamellae (1, 2). A sheet thickness (29) of a shaft spring is dimensioned such that the height of the shaft spring in an axially compressed condition is thinner than the friction lining in a worn out condition.
